If objects can be infinitely large, doesn't it follow that they can be infinitely small? If that's true, then isn't every space, no matter how small, also infinite in it's proportions when seen from the correct perspective? Lets say I had a spaceship in my living room and had the ability to shrink myself as small as I wanted to. If I continued to shrink and accelerated forward (towards the wall) at the same rate as I was shrinking, wouldn't I simply go on forever without ever reaching the wall? Is there a point where if something is so small it simply pops out of existence?

Does anyone know? Please, cite your sources, don't just "of course look at (insert celebrity name here) LOL!!!!!!!1" me.
